1 Claim. (Cl. 15-29) This invention relates to an, all purpose, electrically driven combinationbrush and hose nozzle assembly.

()ne of the main purposes of the invention is to provide a brush as described which will be particularly adapted, though not necessarily limited to, the washing and polishing of cars. Heretofore, it has been customary to carry a hose in one hand, and a sponge or brush in the other, and this has been a relatively inconvenient arrangement, as well as one in which a completely accurate control of the discharge of the water cannot always be assured.

Another object of importance is to provide a brush as stated which, by reason of being power driven, will reduce measurably the physical exertion necessary to clean the surface to which the brush is applied, this being true both with respect to washing and polishing operations.

Another object of the invention isto provide an all purpose brush, to be used anywhere in the home for washing and polishing woodwork, furniture, fioors, etc.

Another object is to provide a brush as described which, when fastened adjacent a kitchen sink, can be used to advantage for washing dishes, bottles, pots, pans, etc.

Yet another object is the adjustment of the nozzle in different directions, in one of which the nozzle points directly toward one side of the brush,so as to discharge water in the area in which the brush is being engaged against the work surface while being rotated at high speed.

Anotherobject of importance is to provide a construction as described in which the entire power driven brush assembly will be carried by a tubular nozzle support member through which the water is caused to flow during use of the device.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

Figure l is a side elevational view;

Figure 2 is a top plan view; and

Figure 3 is a sectional view taken along the line 3-3 of Figure 1.

The reference numeral has been applied to an elongated, straight, tubular member 10. While in the present instance the tubular member 10 is illustrated as being straight substantially from end to end thereof, it could in some commercial embodiment be curved longitudinally if desired.

At its inner or inlet end, the tubular member 10 is provided with a removable, threaded connecting fitting 12, engaging in one end of a conventional valve 14 having a depressible, trigger-type handle 16, the other end of the valve being connected by a similar fitting 18 to a length of flexible hose 20 extending from a source of water under pressure.

At its outlet end, the tubular member 10 has a reduced portion 21, merging into a ball socket 22 in which is engaged a flange of spherical shape 24 formed upon the inner end of a nozzle 26 of hook or L-shape. As will be noted from Figure l, the flange and ball socket are so arranged relative to one another and to the nozzle, as to Patented Aug. 6, 11957 ICE cause the inner end portion of the nozzle to rotate about an axis related at an obtuse angle to the longitudinal center line of the tubular member 10. Further, the nozzle may have limited movement about a transverse axis passing through the ball socket 22, toward and away from the brush head of the device, and also from side to side.

An elongated, straight conduit 28, of aluminum material or the like, is engaged in longitudinal contact with the underside of the tubular member 10, and is secured fixedly to the tubular member 10 by spaced clamps 30. The conduit 28 is substantially smaller in diameter than the tubular member 10, and the clamps 30 are each formed with communicating portions of different diameters receiving the tubular member 10 and conduit 28 respectively, the smaller of said portions merging into contacting ears through which passes a connecting screw.

Adjacent the inner end of the conduit 28, there is mounted upon the tubular member 10 a switch 32, from which extends a cord 34 adapted to be plugged into a conventional outlet, not shown. From the other side of the switch 32 extends a pair of leads 36, said leads extending through the conduit 28 and being connected to opposite sides of a motor 38 secured by a marginal series of bolts or rivets to an attaching plate 40 of circular outer configuration integrally formed upon the tubular member 10 adjacent the ball socket 22. The shaft of the motor has detachably but fixedly connected thereto a brush head 42 having a circumferential series of depending bristles 44 to which the discharge end of the nozzle 26 points.

In use, one may cause water to be directed under pressure out of the nozzle, by depression of the trigger 16, with the brush head being left in a non-rotating condition. The brush head can thus be simply wiped over the work surface, and the water emanating from the nozzle 26 can permeate the brush head to facilitate the operation.

Alternatively, the motor 38 can be turned on by means of switch 32, and with the brush now electrically driven at high speed, water can be directed out of the nozzle 26 either directly into the bristles 44, or onto the work surface adjacent said bristles. Water can be turned on and off while the brush head is rotating, and similarly, the brush head can be stopped in its rotation whenever desired while water is being applied.

Further, the nozzle can be turned in various directions, and can be turned oppositely to the position shown in Figure 1, so as to facilitate washing of the car without accompanying brushing.

It will be understood that the brush head can be removed whenever desired, and a different type of brush head, sponge, or other device, including for example a lambs wool bonnet for polishing purposes, can be applied to the motor shaft, and can be connected thereto with speed and ease, for rotation by the motor. Similarly, in some commercial embodiments, it may be desirable to permit complete removal of the nozzle 26, for substitution of dilferent types of nozzles.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

A tool of the class described comprising an elongated tubular member adapted for connection to a source of cleaning liquid, said tubular member having a main portion of a constant diameter extending substantially the full length of the tubular member, said main portion terminating a short distance inwardly from one end of the tubular member and the tubular member, for thedistance between said one end thereof and the main portion, being of reduced diameter, said one end of the tubular member terminating in a substantially spherically shaped ball socket element opening downwardly, forwardly of the tubular member; a power brush assembly carried by said tubular member, said power brush assembly including an attaching plate of circular outer configuration formed with a marginal series of apertures, said attaching plate having an integral connection to the tubular member and being disposed in a plane parallel to the length of the tubular member, the attaching plate being disposed immediately adjacent the reduced portion of the tubular member on the main portion of said member, and a motor having a base plate contacting and apertured like the attaching plate, whereby to receive fastening elements passing through the attaching and base plates, so that the motor is fixedly connected to the tubular member inwardly from said one end thereof, the shaft of said motor extending normally to the axis of the tubular member, said assembly further including a rotary brush head connected to the shaft of the motor and rotating in a plane parallel to the length of the tubular member; and a nozzle carried by said one end of the tubular member, said nozzle having a flange of spherical shape received in the opening of the ball socket, the nozzle being formed as an elongated tube having end portions substantially at right angles to one another, one of said end portions constituting an inlet portion and the other constituting an Cit outlet portion, the tube being of subsantially constant diameter from end to end thereof, said inlet end portion being the portion formed with the ball socket so as to be a part of the nozzle connected to said one end of the tubular member for rotation about an axis extending longitudinally of said inlet end portion and disposed at an obtuse angle to the length of the tubular member, whereby to effect rotatable adjustment of the outlet end portion about said axis in a plane oblique to the length of the tubular member and obtusely related to the plane of rotation of the brush head, said inlet end portion of the nozzle, through the ball and socket connection between the ball socket and flange of the nozzle, being swingable on the tubular member about any of a plurality of axes extending transversely of the tubular member, in each position to which the inlet end portion is rotated about the axis extending longitudinally thereof, said nozzle and power brush assembly both extending laterally from the tubular member at the same side of the tubular mem-. ber, said outlet portion of the nozzle, in one position to which the nozzle is rotatably adjusted, pointing rearwardly along the tubular member toward the brush head.
